TW1722 features a novel 25 mm dual feed wideband patch element, which provides a truly circularly polarized response, with a typical axial ratio of less than 2.0 dB over the full bandwidth.
TW1722 contains a pre-filter to protect against saturation by high-level sub-harmonic and out-of-band signals, such as LTE and WiFi. As well as a two-stage low-noise amplifier (LNA) with a mid-section filter.
Tallysman‘s TW1722 has a built-in 35 mm circular ground plane should ideally be augmented with a local system ground plane or reflecting surface (DC connection not required).
TW1722 is also available in a compact IP67 Housing TW4722 Magnetic GNSS L1 Antenna Pre-filtered.
